I get that some people don’t like having to ensure they have spare batteries on hand wherever they are. Since I’ve had to do this for 25+ years, I couldn’t care less. Until a rechargeable actually lasts me more than 16 hours, disposable is the way for me. I have Audeo L90-RT and would gladly give up the R and T and tap control for L90-312. Even if the lifespan were 2-3 days, I’d survive, though I suspect it’s at least a few days longer.
I travel frequently. 16-20 hour days, sometimes longer, are a normal occurrence for me. The annoyance of having to stop somewhere along the way to pop them out and put in a charger, even if it’s just 20 minutes (and for my peace of mind I try to do 30+ minutes of charging), really impacts the flow of my day. I don’t like not being able to hear even for that brief period, particularly if I’m at an office or mid-travel.
I would love a trade-in option to switch over. 18 months between Audeo L-R/RT/RL and L-312 releases is absurd. Since a trade is not possible, at this point I’m going to deal with it until LE Audio is more widespread since that will most likely come in the next generation of Phonak devices anyway, and there might be some Auracast public facilities by then.
